In the Book of Mormon, Abinadi (BoM ArabicابيناديAbīnādī) is a prophet who visits the court of King Noah at Lehi-Nephi, and pleads for them to repent of their iniquity. The wicked Noah has him burned with fire. One of Noah's priests, Alma the Elder, adheres to Abinadi's message, eventually become a prophet himself.
The power of the spirit in Abinadi was sufficient that it became a visible "luster." We do not read of such a visible expression of the spirit's protection in an incident between Nephi and his brothers, but clearly Nephi warned his brothers just as Abinadi has warned his would be captors.
In that case, it is Abinadi's purpose to show that they are mistaken in removing Christ from their teachings, and therefore he must show that the law of Moses is not as powerful nor salvific as they preach.
Abinadi's evidence for the hardness of the hearts of the Jews concerning this part of the gospel is interesting as it can come from only two discernible sources.
